Lip Aging Explained: How to Keep Your Lips Looking Young

Article last updated: June 9, 2024

Lips—our most expressive facial feature—are also one of the first areas to show signs of aging. In this article we're covering the reasons behind those subtle changes and exploring the steps we can take to keep our lips looking lusciously youthful.

How Our Lip Skin Differs

Unlike the rest of our skin, the skin on our lips is incredibly thin and delicate. This thinness is primarily because the skin on our lips consists of only three to five cellular layers compared to the 16 layers found on other parts of our body. In fact, our lips don’t have the protective outer layer known as the stratum corneum, which makes them more susceptible to environmental damage. The absence of this barrier layer means that our lips have little defense against harsh weather conditions, pollutants, and UV radiation, all of which can accelerate aging.

Additionally, our lips lack the protective outer layer known as the stratum corneum, making them more susceptible to environmental damage. Without sebaceous glands, lips cannot produce natural oils, leading to dryness and chapping.

This thin structure allows underlying blood vessels to show through, giving lips their characteristic red or pink color. However, the absence of melanin makes lips highly vulnerable to sun damage, which can break down collagen and elastin fibers, leading to thinning and wrinkles.

Factors Influencing Lip Aging

Several internal and external factors contribute to the aging process of our lips:

Internal Factors

Reduction in Collagen and Elastin Production

Internally, the natural reduction in collagen production as we age leads to thinner, less plump lips. Collagen is a protein that provides structure and fullness to our skin, and its decline results in thinner, less plump lips. Elastin, another crucial protein, decreases as well, leading to reduced elasticity and firmness.

Genetic Influence

Genetics also play a significant role in how our lips age, determining the baseline thickness, shape, and resilience of our lip tissue.

Hormonal Changes

Hormonal changes, particularly in women, can also impact lip aging. For example, the decrease in estrogen levels during menopause can lead to a reduction in lip volume and moisture retention, making lips more prone to dryness and wrinkles.

External Factors

Sun Exposure

Externally, sun exposure is a major culprit in lip aging. Ultraviolet (UV) rays from the sun can penetrate the delicate skin of the lips, damaging collagen and elastin fibers, and leading to premature aging. This photoaging process can cause discoloration, loss of volume, and the development of fine lines.


Habits like smoking can significantly accelerate lip aging. The repetitive motion of puckering to smoke, combined with the exposure to harmful chemicals in cigarettes, can cause deep vertical lines around the mouth, often referred to as “smoker’s lines.” Smoking also impairs blood flow to the lips, reducing the delivery of oxygen and essential nutrients, which further contributes to aging.

Lip Licking

Even something as seemingly benign as frequent lip licking can have adverse effects. While it may provide temporary relief from dryness, the constant moisture evaporation leaves lips even drier than before. Saliva also contains enzymes that can break down the delicate skin on the lips, leading to chapping and increased vulnerability to environmental damage.


Dehydration is another factor that can impact the appearance of our lips. When the body lacks sufficient water, the lips are among the first areas to show signs of dehydration, becoming dry and cracked.

Poor Nutrition

Similarly, poor nutrition, especially diets lacking in essential fatty acids, vitamins, and minerals, can affect lip health and hasten the aging process.

Environmental Factors

Environmental factors such as wind, cold weather, and pollution can also contribute to lip aging. Harsh weather conditions can strip the lips of their natural moisture, while pollutants can cause oxidative stress, further damaging the skin.

How To Keep Your Lips Looking Young

The good news is that there are plenty of ways to combat the signs of lip aging! By incorporating a comprehensive anti-aging lip skincare routine, you can maintain smooth, plump, and youthful lips.

Daily Lip Care Routine

Always Use A Lip-Screen

Prevention is key, and it starts with good habits. Always use some sort of Lip-Screen (sunscreen for your lips, obviously) to help protect against the damaging effects of the sun – the higher SPF the better; UV rays can break down collagen and elastin, leading to premature aging, so sun protection is essential.

Get a Moisturizing Lip Balm

Use a nourishing lip balm regularly to keep your lips moisturized and protected. Opt for balms that act as occlusives, which form a protective barrier over the lips to lock in moisture and prevent dryness. This barrier helps to maintain hydration by reducing water loss, ensuring your lips stay soft and supple throughout the day.

Weekly Lip Care Routine

Exfoliate With A Lip Scrub

Incorporate a gentle lip exfoliation routine once or twice a week to maintain smoothness and promote cell turnover. Use a lip scrub or a soft toothbrush to gently remove dead skin cells, revealing fresh, soft skin underneath. Look for scrubs that contain fine sugar or natural exfoliants, combined with moisturizing ingredients like honey or coconut oil.

Use A Lip Mask

Use hydrating lip masks regularly to give your lips an extra boost of moisture. These masks can be left on overnight or used during the day to deeply nourish and rejuvenate your lips. Look for masks with ingredients like hyaluronic acid, vitamin E, and shea butter for maximum hydration.

Overnight Treatments

Consider using overnight lip treatments or masks that work while you sleep. These treatments are often richer and more intensive, providing deep hydration and repair. Ingredients like lanolin, honey, and vitamin E are particularly beneficial for overnight use.
